To ALL wHoM 1r MAY coNcERN:

Be it known that I, MORITZ WOLF, of Philadelphia, in the county of Philadelphia, and State of Pennsylvania, have invented a. new and improved Carpet-WeavingMachine; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the saine, reference being had to the accompanying drawings, forming part of this specification.

Figure 1 represents a sectional elevation of my invention. Y

Figure 2 is a plan or top view of the same, partly in section.

Similar letters of reference indicatecorresponding parts.

This invention relates to a new arrangement of the jacquard-attachment of a earpet-loom, and consists i the use of a double set of needles, by which the harness is operated. V

Two igure-cylinders are employed, one for each set of needles. l

One cylinder' is provided with figure-cards, in the usual manner, and raises as many of the ,vertical needles, which constitute one set, as haveto be lifted, according to the pattern.

The vertical needles which are raised, elevate the ends of the horizontal needles, which constitute the other set; and those'horizontal needles, which are thus elevated, will, at the next stroke of the upper cylinder, which has only holes, but no cards, be thrown back, as they will not fit into the holes ofthe cylinder, and thereby the threads of the harness, with which such needles are connected, will be thrown on to the lifter or` knife, so as to be elevated by the same during its next move.

By this arrangement, the card cylinder has only to make one motion during four moves of the treadle, and, as the cardeylinder can be divided into sections, one whole width, or any suitable part of the machine, can be kept in operation. ,l

A. A are the ordinary horizontal needles of a jacquard-attachment.

The same are connected with vertical threads,iB B, which are suspended from the upper part of the frame C, in which the parts constituting this machine are held. Y

These threads B are connected, at their lower ends, with the threads of the warp.

Each thread B passes through la hole in one of the lifters or knives D D', said lifters being operated by means of levers a and Zi, respectively, from rock-shafts E and E', in the ordinary manner, and connected with the heddles, as usual. 4

Each hole in the lifters has a narrow extension, as shown, into which the thread i-s thrown when the needle A, with which it is connected, is thrown back; and, -when the lifter is raised, it will hold the thread by means oi' a knot, c, inthc` same, and lwill thereby elevatethe thread of the warp with which the said thread Bis connected.

The threads B, which are connected with thev ground-threads of the warp, pass through holes in the liftei D, while those holding thc figure-threads pass through the holes in the lifter D.

Thus, as the shafts E and E are alternately oscillated, the lifters'D and D are alternately raised, and, by them, all the threads B, which are thrown back by the needles A. When the lifter Dis raised, the warp-ground threads required for the pattern will also be raised, while,'with the lifter D', the warpefigurc threads will be raised.

Theheedles A1A reach, with their ends, to a cylinder, F, which is provided with holes on its four sides, the end of every other needle fitting into the hole on every other face of the cylinder, unless they are raised, as hereinafter described. If the needles are raised, their ends fit against the face ofthe cylinder, andi are thrown' back, so as to throw their threads B into the slots' of the lifters.

Each needle A ts, near its end, through a loop or ring formed on a vertical needle, G, a series of such needles, G, being arranged above a card-cylinder, H.

The same is made with four or more sides, as usual, and the card-chain is arranged around it in the ordi nary manner. v Y

The lower ends of the needles'G rest upon the pattern-cards, unless they fit through the holes in thesamei' Such n eedles Gr which do not fit through holes in the pattern-cards are raised, and with them are consequently raised the ends oi' those needles A which are connected with such needles G, so that the said needles A are prevented from fitting into the holes in thescylinder F. Thereby the threads B, connected with such needles A, will be thrown into the slots of the holes in, the liftcrs, and the warp-threads connected with them will be raised.

The cylinder F is revolved duringl each motion of one ofthe rock-shafts, or E', it'being hung in a swinging frame, d, which is operated, by means ot' bell-cranks e e and ropes ff', by either lifter, D'or D, as the same is raised. v

A hook, g, hinged to the frame C, and tting over pins 7l, on the cylinder F, turns the santelone-quartclr revolution during each motion of the litters, and a sliding foot, t', operated by a spring, j, bringsthe cylinder into the right position after each turn. l n

The cylinder H only moves once during every four motions of the treadle or lifters.

It is hung in a rocking-frame, Ic, pivoted te the frame C, the hack end ofthe frame k being connected with vertical strings Z, which are, at their upper ends, tied to springs in, fitted upon the upper b'onrd ofthe frame C.

These strings nt through holes in plates n, extending from the igurevlifters D', said holes having slots'like those of the lifters.

The strings lare also connected with needles a, reaching to the cylinder F, and fitting into holes in the same.

Three sides of the cylinder F have holes, to receive the ends of the needles 0,'(see fig. 1,) but the fourth ide has none; and thus, during every fourth move, the needles o are thrown back. The strings l are thereby thrown into the slots ofthe holes in the plates n. When the lifter D is raised, the strings will also be carried up, having knots for the purpose, and thereby the frame k will be turned, so as to throw the cylinder H into gear with the hooks p, whereby the same is turned. A spring-foot, 1', throwsand holds it in position.

The cylinder F requires no card-chain, it only, by its regular holes,separating the elevated needles A from those which are not elevated.

The cylinder H can be made of two or more independent sections, as shown in iig. 2, for the purpose oi allowing the application of the machine to a pattern of the full width of the machine, or to one which is only partly as wide. The motions of the lifters are as follows:

During the first move, the shaft E is turned. Thereby the lifter D is elevated, and raises ,thosegroundthreads which have been acted upon by means of the pattern-cards. A

During the second move. the shaft E is moved, and the lifter D elevated.A The same raises the required figure-threads.

Duringl the third move, the shaft E is turned with the same effect as duringthe iirst mov-e; and,vdurin g the I fourth move, the motions of the second move are repeated.

During this fourth move, the cylinder H is turned, and a new pattern-card brought into action.

The object of this carpet-weaving machine is to make, with a machine having au equal number of needles as the ordinary machines now in usc, indesign oi' twice the width as can be donc with the ordinary machine.

Thusat present, on an ordinaryjacquard-machine, for a pattern of two hundred and seventy-two needles, the carpet can only he woven half a yard wide, although ten hundred and eighty-eight threads are held by the needles, as each needle is connected with two threads' ofthe ground, and two for the design, while on my machine, with thesam'e number of needles and threads, the carpet lcan be woven a full'yard wide, without using a more expensive machine, nor more complicated cards.

Patterns can, by the aid of this machine, be considerably changed and varied without niuch expense. As the needles A are not -operated directly by the Patternmylinder, they being rst raisediand then pushed, to connect the threads with the lifters, the upper connecting-cylinder F can be at once provided with holes in such a manner as to produce double threads or double carpet-stuil`. For example, if, on thelower patterncylinder A, the cards are not perforated,`so that all the needles G will be raised, and if only black and red warp-threads were used, the whole carpet would be red on the surface, and black on the under side. Ii the cards are perfo` rated, so as to receive al1 the needles G, then the carpet would be black on the surface, and'red on the under side. This shows that, if a red iiower is to be introduced, the requisite number of needles G is to be raised.

As thepattern-cylinder A only changes its position once during four throws, twelve hundred threads-can be made with three hundred cards.

The threads must run down vertically to the treadles, and alongsideof each other, so that the thread which connects with two pattern-threads and that which carries two groundthreads will be close to each other. 'Without such a vertical arrangement of threads, it would4 be impossible to make carpet a yard wide with but two hundred and seventy-twoineedles.

As the pattern-cylinder is divided intod two or more sections, the pattern can be frequently changed by setting the sections in difi'erent order.

"i Having thus described my invention, I claim as new, and desire to secure by Letters Patent- 1. vOperating the cylinder A by means of the cylinder F, needles o, strings Z, slotted extension vt of the lifter D', and frame K, all made and operating substantially as and for the purpose herein snown and described.

2. Two or more independently-acting cylinders, in combination with the vertical needles, substantially as described, Afor the'purpose specified.
